and hasl for'its object to provide a construction inwhich the-products of combustion and y obnoxious anddangerous gases will be eii'ec` sought to be clearly defined by the claims,

' radiator in full lines;

futed from the heating medium. f

tually 'carried off' andf-the air in thehover kept fresh and pure,` 1 and inzwhich alsothe maximum heat will beobtained and distri To the' accomplishment of the foregoing and such other objects a's'may hereinafter appear theinvention 'consists fin the features hereinafter. particularly describedV and then may be supportedV upon aV iioor lor suitable base at a suitable distance above the same and having `at its base alianging apron or curtain V3 which may be slitted or separated at suitable intervals for the easy egress and.y

Y the hover for the chicks@ i ingresstoV and from beneath the dome or mii-es housing the interior of 1 which consti l/Vithin the cone or housing there is supported by bracketsc, or otherwise, a cone- Y shaped meinber' having ananniilar or ringl like base 6 and consisting-eta number of formed rprei'erably with vertical side wallsV A y V11 and converging top 12 and .within which may be` made therein' withoutl ,departing parallel passage-ways 7 communieatingV one Y with the otherat one end, as illustrated at 85 the innermost passageway having depending from its upper end a tubular neck 9 from which is supported 'a hollow cap 'member 10 Y is suitably suspended, say by* a. rod13, a. conical delector 14, 4the walls of which are i -ormed "with perforations 15. The outermost passage-way opens at'its upperendinto a -flue 16 which may be'provided witha damper 17 to control the escape of outflowing currents traversing the parallel communicating passage-ways mentioned. ABeneath the cap 10 there is suitably supported an oil burner or lamp 18 to vwhich oilgunder con-y trol by a valve 19 is supplied `from a'suitg ableoil reservoir 20, the chimney 210i theV lamp extending up into the caplOk asil- Y lustrated The productsof combustionfrom the Ylampy or heater discharge intothe vcap 10 and are deflected bythe bell-.shaped de-` l .lectofrso als tobe directed `'between it and the inclined top o theicap and out throughfthtl neck V9 int-o the upper endgof` the innerinost passage-'way-V 7 andi r'oinvthe same,j atits lower y end,l into ithfe" outermost'passage-way 7 and rom'the'jfiipper end of: the samefinto cci the lluev 16; Fro1n thislue the escaping products pass into an exit pipe 22y whichi discharges into the lower part of anv annular shaped drum 23l and from the upper portion f of the same into a 'pipe 24 .to which is attacheda discharge pipe 25,'fleading to -a properv point outsideof the compartment or structure in Vwhich the brooderis located. Y The: drum 23 affords large radiating surface,

andv airis tree to `.circulate through 'the cen# tral air space 26V ofthe drum formed by the annular'construction of the drum. *Whl yitis preferred to use-the annular `drum as apart ,oztthe'brooder because `of the advanfeatures of constructionretained Underfthe particular construction and ltagesY arising from its use Y et twcan. be omitted'andthe flue lexten ed directly to make connection witlilthe lfinal discharge-1 pipe 25, and the f advantages lof the other rangement of passage-waysdescribed aj strong circulation rof airfand thevprofducts ofv combustion' is obtained `so that all injuriousy gasesv are expeditiously drawn outl oi the f at a temperature best calculated for broodf ing purposesjas thelarge heat radiating sur-V tace obtained by the described construction penditure 'of'fueh W ticularity the preferred `details but changes `,broode'r and at the saine time a'good circii-` c lation of pure air obtained in tlieihover and promotes the best results and at theleastex-`^` from thescope ofthe-invention ,as sought y toy befdened by the"apper'idedclaims.A Having describedp-my Y inventio forth its ineritswlia'tl claim is z-f Y tri'cally ,positioned walls orminga cone` shaped heat circulating Vchamber spaced fromvsaid dome, aheat spreading .partition member withiny said cone shaped heat circulating chamberythe upper end of said heat y circulating chamber. beingl connected fwith an exit iiue'and theother end of said heat circulating chamber being provided with la Vlla f downwardly depending collar portionrsaid collarfportion having anannular skirt conwithin said downwardly depending' col'lai portion for securing uniform distribution of heat 1n said heat circulating chamber.

2. A broeder comprisingv in combinationa heating device, a pluralityof conical shaped i hood members, one of said hood members forming a 'housing for-the others'of said hood members, a .pair'oif saidhood members J being closed at their lower ends forming a heat circulating.,chamber, [an'exit flue connected to the top of one of said last named hood members and a depending collar mem-` ber connected with the inner periphery of the other of said pair of hood members immediately'below said 'exit flue,V a source of heat locatedvbelow saidl collar member, and 20 a pair of conicalshaped members disposed i in the path of travel of heat from said sourcerone; of said vconical shaped members being'situated'in said collarV member and the other of said conical shaped members being' located in said heat circulating chamber for securing uniform distribution ,of heat throughout the brood-er.
